Thermomechanical treatment of high-carbon wire rod in the 150 high-speed wire mill at Belorussian Metallurgical Plant

Abstract

The introduction of a reduction and calibration unit at a wire mill is recommended for the production of high-carbon wire rod subjected to thermomechanical treatment with controlled rolling and cooling. By this means, the fluctuation in the mechanical properties may be reduced. In addition, the decarburized layer will be thinner and uniformly distributed over the perimeter of the wire rod. As a result, the plasticity of the wire rod in subsequent processing is improved, while the formation of quench structures at the wire surface in high-speed drawing is practically eliminated.
